Extractionofthemaincomponents
Matlab提取主分量矩阵。程序设计步骤:
1、去均值
2、计算协方差矩阵及其特征值和特征向量
3、计算协方差矩阵的特征值大于阈值的个数
4、降序排列特征值
5、去掉较小的特征值
6、去掉较大的特征值(一般没有这一步)
7、合并选择的特征值
8、选择相应的特征值和特征向量
9、计算白化矩阵
10、提取主分量()

Integration_separation_PID_Controller
说明: 该算法连续系统的积分分离式PID算法,用MATlab开发,能够管直接运行,当控制量与设定值偏差较大时,取消积分作用,以免积分作用过大引起系统的稳定性降低。(The algorithm of the integral continuous system separate PID algorithm, developed using Matlab and can directly run the tube, when the control volume and settings deviation is larger, the abolition of integral action, so as not to cause too large integral role in the stability of the system lower.)

说明: 七单元天线阵DOA估计
clear clc
d=1 天线阵元的间距
lma=2 信号中心波长
q1=1*pi/4 q2=1*pi/3 q3=1*pi/6 q4=3*pi/4 四输入信号的方向
A1=[exp(-2*pi*j*d*[0:6]*cos(q1)/lma)] 求阵因子
A2=[exp(-2*pi*j*d*[0:6]*cos(q2)/lma)]
A3=[exp(-2*pi*j*d*[0:6]*cos(q3)/lma)]
A4=[exp(-2*pi*j*d*[0:6]*cos(q4)/lma)]
A=[A1,A2,A3,A4] 得出A矩阵
n=1:1900
v1=.015 四信号的频率
v2=.05
v3=.02
v4=.035
d=[1.3*cos(v1*n) 1*sin(v2(we)
